DesignatedPointType
fb:DesignatedPointType
A named geographical location used in defining an ATS route, the flight path of an aircraft or for other navigation or ATS purposes. [FIXM] The coded designator of a designated point is not always sufficient for unambiguously referring to that feature: The 5-letter coded designator of a waypoint is supposed to be unique world-wide (according to ICAO Annex 11), but in reality it is not. The combinations of fields that would make the references unique are name + position. This FIXM class adds an optional properties 'position' which may be used as a complement to the 'name' information in order to remove any ambiguity on the coded designator.
| Properties | Definition | Type |

| designator | The name of the designated point. | fb:DesignatedPointDesignatorType |
| extension | An extension hook for attaching extension (non-core) classes. | fb:DesignatedPointExtensionType |
| href | Provides an optional mechanism enabling FIXM aeronautical fields to be supplemented with references to AIXM features. This field should be considered functionally equivalent to the xlink:href field used in AIXM to reference features. [FIXM] | fb:HypertextReferenceType |
| position | The values of latitude and longitude that define the position of the Designated Point on the surface of the Earth with respect to a reference datum. [specialised from ICAO Doc 9881] This optional field may be used to achieve unambiguous reference to the designated point.
